There are some horrors in history that are so evil that human beings want to try and forget them, but we must never do that with the Holocaust, because it was a horror perpetrated almost in plain sight, and it is the banality of the evil and the fact that it happened over years that stands out as well: a railway that was built to take people to gas chambers to die, queues of people to be processed, a web of deception and betrayal, families like the Franks, with Anne and her diary, that were ripped from hiding places and thrown to be slaughtered. 

Minister, Hugo Rifkind wrote a remarkable blog about the Holocaust in 2015 emphasising how important it is that we continue to talk about the fact that it was what people did—the people. This is what I'd like to ask you about. He focuses on how easily it happened, how, although people who killed and the people who were killed had grown up alongside one another, some of them identified traits that they wanted to wipe from the face of the earth. Rifkind said:

'The dead and killers alike knew china teapots, Mozart, varieties of cheese.... Then, one day, they...began to slide towards something else.'

So, Minister, do you agree that this is one of the principal reasons we have to mark this day, because that slide into horror is something that can lurk beneath the most seemingly civilised of societies, of times—that we cannot take for granted that that was another place, another time, that it can never be safe to bury it in history's tide?
